Morning Fred. I contacted Summit Racing yesterday and Wilword has a kit WIL-140-11023. Uses the original spindles and a 4" pattern. 790 US. Not sure if you get the proportioning valve or not I forgot to ask. For the amount of driving I do a year I'm sticking with the drum setup. I already have a brand new drum, it came with the car. I can get a new repop Drum from National Moparts for 100 bucks if needed. Should be able to get one good drum out of the two that's on the car now. My wife was ok with going ahead with the conversion but just can't justify it when I drive 800 miles at the most a year.
